Once that is done, a complete three-byte MIDI note-on message can be sent with three “ Serial.print(val,BYTE)” commands. This is easily done with “ Serial.begin(31250)“. First is that to implement a MIDI interface, all you really need is the ability to send serial data at 31,250 bps. The code has a few tricks that may not be immediately obvious. The 5.1v zener diode is there to insure any large voltages don’t make it into the Arduino and blow it out. (Note: depending on what kind of MIDI connector you’re usign (jack or cut-off cable), you may need to swap the connections to MIDI pins 4 & 5).įor the piezo input, the 1M resistor is to bleed off the voltage generated by the piezo when it is struck. The hardware is an Arduino board with a MIDI jack, a few buttons, and two piezos attached to it. Hide piezo sensors around the house during your Halloween party to trigger scary sounds when people walk around! Here’s a quick project using techniques from this week’s class that turns an Arduino board and a few buttons and piezos into a MIDI drum kit or scary sound trigger.

The notes for the fourth and final class are up on the Spooky Arduino class page.
